JOURNAL-BOX AND DUST-GUARD.

Specification of Letters Patent.

iratenteo. May 8, 1906.

Application filed August 17,1904. Serial No. 221,042.

lmore city, State of Maryland, have invented certain new and usefulImprovements in Journal-Boxes and Dust-Guards; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. This invention relates to journal-boxes for railway-cars, and more particularly to means forpreventing ingress of dust around the journal, the object of theinvention being to provide an outside guard which will be held securelyin place against the inner end face of the box, while permitting oflateral movement of the guard-plate as well as vertical movementcorresponding to the shifting position of the journal relatively to thebox.

A further object of the invention is to provide such a shape andarrangement of parts as will relieve the holding-springs to a markeddegree and will at the same time obviate the tendency of the packing tocreep out through the journal-opening at the inner end of the box.

An additional object of the 'invention is to provide against rapid wearof the guard-plate upon the journal.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure l is a vertical section through the inner end portion of theournal-box and a dust-guard plate embodying the present invention. Fig.2 is a section on line 2 2 of Fig. 1. Fig. 3 is a view similar to Fig.1, illustrating a second embodiment of the invention. Fig. 4 is asection on line 4 4 of Fig. 3. Fig. 5 is a view similar to Fig. 1,illustrating a third embodiment of the invention. Fig. 6 is a section online 6 6 of Fig. 5. Fig. v7' is'an end view of the j ournal-box.

Referring now to the drawings, and more particularly to Figs. l and 2thereof, there is shown a portion of a journal-box 10, in the rear orinner end of which is formed the usual opening 11 to receive the journal12. As

journal-boxes are ordinarily constructed the inner end faces thereof arevertical, so that when an outside dust-guard is employed the entireweight of the plate and the parts carried thereby is carried upon thejournal with the exceptionof such part of the weight as is supportedbythe means which clamps the plate against the end of the box. The extentto which this clamping means supports the plate is determined by thefriction with which it holds the plate against the end of the box, andthis friction must not be so great as to materially interfere withsliding movement of the plate over the face of the box. In the presentconstruction the inner end face 12 of the journal-box slants, so thatthe bottom thereof lies closer to the car-wheel than its top, and fromthe upper and lower faces of the journal-box project iianges 13 and 14,respectively, the rear or outer faces of which form continuations of theface 12, as illustrated. The opposite or front faces of the flanges 13and 14 are beveled at their end portions, as shown at 15 and 16 in Fig.2, the intermediate portion 17 forming apressuresurface to receive theclamping-spring of the guard-plate, as hereinafter described. The

guard-plate 18 has a central opening 19, which snugly receives thejournal l2, and upon .the inner face of this guard-plate is formed anannular flange 19', which makes direct contact with the face 12 andwhich under working conditions soon wears to a smooth contactingsurface, which by fitting close against the face 12 effectually preventspassage of dust between it and said face. In use the wall of theAopening 19 gradually wears, the maximum wear being of course at theupper portion of the wall, and to retard this wear a boss 20 is formedupon the outer face of the plate 18, the free end face of this boss inuse being vertical and standing at an acute angle to the inner face ofthe guardplate, so that the upper portion of the boss is thicker thanthe lower portion and a greater surface is in contact with the journal,thus reducing the wear. The guard-plate 18 extends above and below theflanges 13 and 14, respectively, and then over the edge of the flanges,and then in the direction of the body of the box in hook shape, as shownat 21 and 22, respectively, there being housings 23 and IOO 24,respectively, formed at the end portions of the bills of thesehook-shaped portions, and in each housing is disposed a helical spring25, the outer end of which bears against the corresponding flange. lnputting the dust-guard plate in place it is moved laterally, so that thehooked portions will engage around the flanges 13 and 14. The helicalsprings first engage the beveled faces 15 or 16, depending upon the sidewith which they are initially engaged, and as the plate is.

slid into place the springs travel along the beveled faces, during whlchmovement they are compressed or placed under increased tension, so .thatwhen the springs nally reach the faces 17 of the flanges they have beengiven the proper tension to hold the guard-plate with its flange 19snugly against the end face of the ournal-boX. l/Vith this constructionthe guard-plate is supported in a large measure by the slanting innerend face of the journal-box, while it has such a freedom of movementlaterally and vertically as not to cause excessive Wear of the plateagainst the journal.

Referring now to Figs. 3 and 4 of the drawings, there is shown ajournal-box 30, having the slanting inner end wall 31, corresponding tothe end wall 29 in Fig. 1 and through which is formed an opening 32 toreceive the journal 33. The rear end or inner end face 34 ofthejournal-box slants in the same manner as the face 12 and against thisface rests the annular flange 35 of the guard-plate 36, which has alsoan openin 37, which snugly receives the journal. On t e outer face ofthe plate 36 is formed a boss 38, which is thicker at its upper portionthan at its lower to present the extended bearing-surface 39. From theupper edge portion of the journal-box 30 at the inner end thereof thereprojects an anglean e 40, and from the lower edge portion of t e boXprojects a corresponding angleflange 41, these angle-flanges formingguides between which and the face 34 the upper and lower edge portions,respectively, of the uard-plate 36 are received. Against the outer faceof the guard-plate adjacent to the upper and lower edges thereof,respectively, are riveted plate or leaf springs 42 and 43, the ends ofwhich are in spaced relation to the guardplate and engage the innerfaces of the portions of the angular flanges parallel with the wall 31.These leaf-springs serve to hold the guard-plate against the end of thejournalboX in the same manner as the springs 25, above referred to. Theguard-plate in this construction also is moved laterally into activeposition.

In the construction shown in Figs. 5 and 6 of the drawings thejournal-box 50 has a slanting rear wall 51 with the corresponding rearor inner end face 52 and with an o ening 53 to receive the journal 54.Againstt e face 52 rests the annular flange 56 on the face of the plate57, having a central opening 58, which snugly receives the journal 54,and having a boss 59, through which the opening 58 is formed, the bosspresenting the extended bearing-surface 60 at its upper portion. Theplate 57 extends above and below the journal-box, and from its upper andlower edge portions project arms 61 and 62 beyond the inner end of theboX, the end portions of these arms being turned away from the boX, asshown at 63 and 64, and having formed transversely therethrough thecurved slots 65 and 66,-leaf-springs 67 and 68 being engaged in theseslots with their end portions projecting therefrom. At the inner endcorners of the top and bottom of the journal-box are pairs ofangle-flanges 69 and 70, respectively, one side of each angle-flangeforming a continuation of the end face 52 of the journalboX or beingflush therewith, while the other member is flush with the adjacent sideof the j ournal-boX. In putting the guard-plate in place the leaf-spring67 is first en aged behind the rear end members of t e angleflanges 69,and the plate is then moved downwardly and its lower end pressed in andthe plate then moved upwardly to engage the leaf-spring 68 behindthelower angle-flanges 70. The journal 54 when in place preventssuicient vertical movement of the ardplate to permit of disengagement ofthe leafsprings from the flanges.

Not only does the slanting rear or inner end wall of the journal-box ineach instance serve to partially suplport the guard-plate, but the innerface of t e wall by slanting upwardly or toward the outer end of thejournal-box prevents the waste or packing from working out through theopening 11 in Fig. 1 and the corresponding openings in the otherfigures.
